A galvanometer has a resistance of `30 Omega`, and a current of `2 mA` is needed for a full- scale deflection. What is the resistance and how is it to be connected to convert the galvanometer of `0.2 V` range?

Text Solution

Verified by Experts

The correct Answer is:
`(##RES_PHY_CE_E01_038_A01##)`
(a) `S=(30xx2xx10^(-3))/(0.3-2xx10^(-3))=0.2013Omega`
(b) `R= 70 Omega`
`(##RES_PHY_CE_E01_038_A02##)`
